I would like to create tranlastion periodicity between two parallel boundary faces.
I am using the GUI, v5.0.3.
Looking at the listing, the creation of the periodic "interior" boundary seems successful, since it states:
Code: Select all
Global number of boundary faces selected for joining: 79656
Element selection successfully done.
Determination of possible face intersections:
bounding-box tree layout: 3D
Global number of intersections detected: 752804
Vertex-Vertex intersections: 741057
Other intersections: 11747
Joining operation is non-conforming.
Global number of new vertices to create: 13254
Equivalences broken for 0 edges.
Edge intersections and vertex creation done.
Pre-merge for 48407 global element couples.
Max size of a merge set of vertices: 6
Excessive transitivity for 0 set(s) of vertices.
Edge removed for 0 faces (global).
Join mesh cleaning done.
Edge removed for 0 faces (global).
Join mesh cleaning done.
Merge vertices and mesh update done.
Global number of faces after splitting: 122651
Global configuration after the joining operation:
Global number of border faces to add: 0
Mesh cleaning done for degenerate faces.
Global number of cleaned interior faces: 0
Global number of cleaned border faces: 0
After joining
Number of cells: 358452
Number of interior faces: 1103329
Number of boundary faces: 33840
Number of vertices: 420974
Joining 1 completed (6.7 s).
All joining operations successfully finished:
Wall clock time: 6.7
is handled, faces having periodic matches do not appear as boundary faces, but as interior faces, and
are thus not available anymore for other periodicities".
On the other hand, opening the BOUNDARY_GROUPS.case in Paraview, the two original faces are not visible anymore after extracting blocks. They are available as "interiorjoinedFaces_j01" in the separated JOINING.case.
Is there a way to double check the correct creation of a periodic boundary condition?
Many thanks in advance.
Best regards,
Daniele
